This market will resolve according to Meta's public market capitalization at the close of regular trading on the final trading day of the specified month. If the determined value falls exactly on the boundary between two brackets, this market will resolve to the higher bracket. Public market capitalization will be determined through appropriate calculation using the final official regular-hours closing prices published for the company's listed equities on its primary exchange for the last trading day of the specified month, multiplied by the company's total number of shares outstanding at the relevant time. If necessary, to accurately capture the company’s total market capitalization, rather than a stock-class-specific market capitalization, the calculation will include all outstanding share classes and apply any stated conversion ratios to the publicly traded class. Where no conversion right exists, such shares will be counted at their stated outstanding amount without discount, unless official filings explicitly specify differently. The number of outstanding shares will be determined from official company filings or disclosures (e.g., SEC filings). If the listed company merges with or acquires another entity and remains the parent company, no change to resolution methodology applies. If the listed company is acquired, merges into another entity and is no longer the surviving parent company, or otherwise ceases to exist as an independent entity prior to the end of the period, the public market capitalizations achieved prior to completion of the transaction will be considered for resolution. No transaction, acquisition, or merger consideration will be considered for resolution. The resolution source for this market is official exchange trading data and publicly reported share counts.Recent Q2 2026 results highlighted Meta’s elevated AI infrastructure spending, with 2026 capital expenditures now guided to $130–145 billion amid higher component costs and data center expansion. This weighed on near-term margins and prompted an 8–10% post-earnings stock decline, leaving market cap near $1.4–1.5 trillion. Traders see the outcome hinging on whether advertising revenue growth can offset these investments while Llama model adoption and platform engagement trends stabilize share price before September’s close. Competitive pressures from rival large language models and potential regulatory scrutiny add further uncertainty, keeping probabilities closely balanced across the $1.00–2.25 trillion ranges.
